Description

Technical Field

[0001] The invention relates to the technical field of aquatic organism breeding, and in particular to an indoor automatic pool separation method for aquatic organisms. Background Art

[0002] my country is the largest aquaculture country, with the total volume of aquatic products accounting for 60% of the world. The rapid development of aquaculture has not only improved the food nutrition structure and prospered the rural economy, but also played an important role in ensuring food security, reducing the number of poor people and protecting the ecological environment. Aquatic products are delicious and high in protein. They can also provide a variety of substances that are beneficial to health, playing a very important role in balancing human nutrition. With the continuous increase in my country's aquatic trade, my country's aquatic product exports have jumped to the first place in the world, accounting for about 10% of the world's total aquatic product trade. Aquatic product exports have reached 10 billion US dollars, and the market prospects are broad.

[0003] In aquaculture production, after a period of cultivation, aquatic organisms in the same breeding pond will have large differences in individual specifications due to their adaptability to the water environment and different food intake. At this time, if the fish are not separated into different ponds according to their size in time, on the one hand, small fish cannot compete with large fish for food, resulting in increasingly serious differentiation, affecting experimental results or breeding benefits; on the other hand, some aquatic organisms have the phenomenon of cannibalism, that is, "big fish eat small fish", which will also cause losses in experiments or production. At the same time, as aquatic organisms grow, excessive water density will also produce a crowding effect, bringing the risk of hypoxia or death.

[0004] At present, the method of sorting aquatic organisms into ponds is mainly carried out manually. According to the observed size of aquatic organisms, large-sized aquatic organisms are scooped out with a scoop net of a certain mesh size, and small-sized individuals are retained and continued to be cultured in the original pond. This method is not only time-consuming and labor-intensive, but may also cause the scoop net to damage the epidermis of aquatic organisms, causing the risk of infection. Based on this, it is particularly necessary to develop an indoor automatic sorting method for aquatic organisms. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an indoor automatic pool separation method for aquatic organisms, which is easy to operate, realizes automatic multiple pool separation of aquatic organisms, saves time and effort, reduces manual operation errors and possible damage to aquatic organisms, reduces infection risks, ensures aquaculture benefits, and is easy to promote and use.

[0013] ⑦ After the pools are divided, close the water inlet valve and the drain valve after the water levels in the breeding pool and the adjacent pool are the same;

[0014] ⑧ If it is necessary to separate aquatic organisms of larger sizes, the number of concentric metal plates stacked on the upper layer in the breeding pond can be reduced and the size of the drain outlet can be adjusted to achieve the effect of automatic separation of aquatic organisms of different sizes;

[0015] ⑨ After a period of breeding, according to actual needs, the smaller-sized aquatic organisms in the adjacent pond are separated into the next breeding pond in the same way, so as to realize automatic multiple separation of aquatic organisms.
